Edward Thomson d711165d 2016-07-22T14:02:00 repository: don't cast to `int` for no reason And give it a default so that some compilers don't (unnecessarily) complain.
Josh Triplett a200dc9e 2016-04-03T19:24:15 Fix repository discovery with ceiling_dirs at current directory git only checks ceiling directories when its search ascends to a parent directory. A ceiling directory matching the starting directory will not prevent git from finding a repository in the starting directory or a parent directory. libgit2 handled the former case correctly, but differed from git in the latter case: given a ceiling directory matching the starting directory, but no repository at the starting directory, libgit2 would stop the search at that point rather than finding a repository in a parent directory. Test case using git command-line tools: /tmp$ git init x Initialized empty Git repository in /tmp/x/.git/ /tmp$ cd x/ /tmp/x$ mkdir subdir /tmp/x$ cd subdir/ /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x git rev-parse --git-dir fatal: Not a git repository (or any of the parent directories): .git /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x/subdir git rev-parse --git-dir /tmp/x/.git Fix the testsuite to test this case (in one case fixing a test that depended on the current behavior), and then fix find_repo to handle this case correctly. In the process, simplify and document the logic in find_repo(): - Separate the concepts of "currently checking a .git directory" and "number of iterations left before going further counts as a search" into two separate variables, in_dot_git and min_iterations. - Move the logic to handle in_dot_git and append /.git to the top of the loop. - Only search ceiling_dirs and find ceiling_offset after running out of min_iterations; since ceiling_offset only tracks the longest matching ceiling directory, if ceiling_dirs contained both the current directory and a parent directory, this change makes find_repo stop the search at the parent directory.
Edward Thomson 62602547 2015-12-26T22:39:22 git_repository_init: include dotfiles when copying templates Include dotfiles when copying template directory, which will handle both a template directory itself that begins with a dotfile, and any dotfiles inside the directory.

Carlos Martín Nieto aebddbe7 2015-09-21T06:01:03 Merge pull request #3434 from ethomson/reservednames Win32 Reserved names: don't reserve names outside the working directory
Edward Thomson 538dfc88 2015-09-17T18:12:05 repository: only reserve repo dirs in the workdir Check that the repository directory is beneath the workdir before adding it to the list of reserved paths. If it is not, then there is no possibility of checking out files into it, and it should not be a reserved word. This is a particular problem with submodules where the repo directory may be in the super's .git directory.
Edward Thomson ac2fba0e 2015-09-16T15:07:27 git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

Carlos Martín Nieto 16c73d38 2015-06-23T20:44:27 repository: check the format version This is something we do on re-init but not when opening a repository. This hasn't particularly mattered up to now as the version has been 0 ever since the first release of git, but the times, they're a-changing and we will soon see version 1 in the wild. We need to make sure we don't open those.
Carlos Martín Nieto 99e11cdd 2015-06-23T20:43:49 repository: don't error out if there is no version git will assume the repository format version is 0 if the value is not there. Do the same.
Carlos Martín Nieto dfda2f68 2015-04-27T19:27:29 submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

For this use-case we provide annotated version of a few functions which let the caller specify what user-friendly name was used when asking for the operation.

Carlos Martín Nieto 9a97f49e 2014-12-21T15:31:03 config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.
Carlos Martín Nieto 4e498646 2015-01-15T16:50:31 repository: remove log message override for switching the active branch We want to use the "checkout: moving from ..." message in order to let git know when a change of branch has happened. Make the convenience functions for this goal write this message.
Carlos Martín Nieto 659cf202 2015-01-07T12:23:05 Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.
Edward Thomson 4196dd8e 2015-02-26T15:33:58 repository: Introduce "reserved names" A repository can have multiple "reserved names" now, not just a single "short name" for the repository folder itself.

Edward Thomson a64119e3 2014-11-25T18:13:00 checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

The rugged tests are fragile 74240afb 2014-09-17T15:35:50 repository: Do not double-free config
Russell Belfer 1fbeb2f0 2014-09-15T21:59:23 Fix attribute lookup in index for bare repos When using a bare repo with an index, libgit2 attempts to read files from the index. It caches those files based on the path to the file, specifically the path to the directory that contains the file. If there is no working directory, we use `git_path_dirname_r` to get the path to the containing directory. However, for the `.gitattributes` file in the root of the repository, this ends up normalizing the containing path to `"."` instead of the empty string and the lookup the `.gitattributes` data fails. This adds a test of attribute lookups on bare repos and also fixes the problem by simply rewriting `"."` to be `""`.
Jameson Miller bc737620 2014-08-20T10:24:41 Introduce option to use relative paths for repository work directory Teach git_repository_init_ext to use relative paths for the gitlink to the work directory.

Russell Belfer 43a04135 2014-05-08T13:52:46 Pass unconverted data when iconv doesn't like it When using Iconv to convert unicode data and iconv doesn't like the source data (because it thinks that it's not actual UTF-8), instead of stopping the operation, just use the unconverted data. This will generally do the right thing on the filesystem, since that is the source of the non-UTF-8 path data anyhow. This adds some tests for creating and looking up branches with messy Unicode names. Also, this takes the helper function that was previously internal to `git_repository_init` and makes it into `git_path_does_fs_decompose_unicode` which is a useful in tests to understand what the expected results should be.
Carlos Martín Nieto ac99d86b 2014-05-07T11:34:32 repository: introduce a convenience config snapshot method Accessing the repository's config and immediately taking a snapshot of it is a common operation, so let's provide a convenience function for it.
Russell Belfer 5269008c 2014-05-06T16:01:49 Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.
Russell Belfer 702efc89 2014-04-30T10:57:42 Make init_options fns use unsigned ints and macro Use an unsigned int for the version and add a helper macro so the code is simplified (and so the error message is a common string).

Carlos Martín Nieto 0b28217b 2014-01-15T12:51:31 refs: remove the _with_log differentiation Any well-behaved program should write a descriptive message to the reflog whenever it updates a reference. Let's make this more prominent by removing the version without the reflog parameters.
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer 9f77b3f6 2013-11-25T14:21:34 Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Russell Belfer 14997dc5 2013-10-08T12:45:43 More filemode cleanups for FAT on MacOS This cleans up some additional issues. The main change is that on a filesystem that doesn't support mode bits, libgit2 will now create new blobs with GIT_FILEMODE_BLOB always instead of being at the mercy to the filesystem driver to report executable or not. This means that if "core.filemode" lies and claims that filemode is not supported, then we will ignore the executable bit from the filesystem. Previously we would have allowed it. This adds an option to the new git_repository_reset_filesystem to recurse through submodules if desired. There may be other types of APIs that would like a "recurse submodules" option, but this one is particularly useful. This also has a number of cleanups, etc., for related things including trying to give better error messages when problems come up from the filesystem. For example, the FAT filesystem driver on MacOS appears to return errno EINVAL if you attempt to write a filename with invalid UTF-8 in it. We try to capture that with a better error message now.
Russell Belfer 5173ea92 2013-10-04T16:32:16 Add git_repository_reset_filesystem and fix tests When a repository is transferred from one file system to another, many of the config settings that represent the properties of the file system may be wrong. This adds a new public API that will refresh the config settings of the repository to account for the change of file system. This doesn't do a full "reinitialize" and operates on a existing git_repository object refreshing the config when done. This commit then makes use of the new API in clar as each test repository is set up. This commit also has a number of other clar test fixes where we were making assumptions about the type of filesystem, either based on outdated config data or based on the OS instead of the FS.
Russell Belfer 840fb4fc 2013-10-03T14:42:37 Update repo init with fewer platform assumptions The repo init code was assuming Windows == no filemode, and Mac or Windows == no case sensitivity. Those assumptions are not consistently true depending on the mounted file system. This is a first step to removing those assumptions. It focuses on the repo init code and the tests of that code. There are still many other tests that are broken when those assumptions don't hold true, but this clears up one area of the code. Also, this moves the core.precomposeunicode logic to be closer to the current logic in core Git where it will be set to true on any filesystem where composed unicode is decomposed when read back.
Russell Belfer af302aca 2013-10-02T14:13:11 Clean up annoying warnings The indexer code was generating warnings on Windows 64-bit. I looked closely at the logic and was able to simplify it a bit. Also this fixes some other Windows and Linux warnings.
Russell Belfer 6b7991e2 2013-09-30T16:13:53 Add check if we need to precompose unicode on Mac This adds initialization of core.precomposeunicode to repo init on Mac. This is necessary because when a Mac accesses a repo on a VFAT or SAMBA file system, it will return directory entries in decomposed unicode even if the filesystem entry is precomposed. This also removes caching of a number of repo properties from the repo init pipeline because these are properties of the specific filesystem on which the repo is created, not of the system as a whole.
Russell Belfer 1ca3e49f 2013-09-23T13:34:01 Clean up newly introduced warnings The attempt to "clean up warnings" seems to have introduced some new warnings on compliant compilers. This fixes those in a way that I suspect will also be okay for the non-compliant compilers. Also this fixes what appears to be an extra semicolon in the repo initialization template dir handling (and as part of that fix, handles the case where an error occurs correctly).

There are related internal objects (git_filter_list) that we will want to publish at some point, but this is a first step.

Carlos Martín Nieto 605da51a 2013-09-17T09:50:30 No such thing as an orphan branch Unfortunately git-core uses the term "unborn branch" and "orphan branch" interchangeably. However, "orphan" is only really there for the checkout command, which has the `--orphan` option so it doesn't actually create the branch. Branches never have parents, so the distinction of a branch with no parents is odd to begin with. Crucially, the error messages deal with unborn branches, so let's use that.
Russell Belfer 42181836 2013-08-29T10:27:01 Treat detached HEAD as non-empty repo This simplifies the git_repository_is_empty a bit so that a detached HEAD is just taken to mean the repo is not empty, since a newly initialized repo will not have a detached HEAD.
